Timed out waiting for transform from base_link to odom

Course Support Mastering with ROS - SUMMITXL
1

Hi all,

I got stuck during “How to navigate without map” with the following warning in the Summit XL tutorial:

[ WARN] [1581375200.707343168, 2328.075000000]: Timed out waiting for transform from base_link to odom to become available before running costmap, tf error: canTransform: target_frame odom does not exist. canTransform: source_frame base_link does not exist.. canTransform returned after 0.1 timeout was 0.1.

Do you have an idea how I can solve this?

Thank you!

Hello @LBrobtcs,

The problem is with the frames. You need to change the odom frame to summit_xl_a_odom and the base_link frame to summit_xl_a_base_link. I’ve updated the course notebooks with the corrected files so that you can check them too.

Best,
